Is is possible to use ECDH with stunnel?
When using s_server and specifying the cipher I can establish a
connection. But when using stunnel and specifing the same cipher, the
connection is rejected with "no shared cipher".
e.g.
openssl s_server -cert server.pem -cipher DHE-RSA-AES256-SHA
It appears the difference is that s_server uses "default temp ECDH
parameters" while stunnel doesn't have a default nor is there a way to
specify the ECDH parameters.
>From what I understand the ECDH parameters cannot be included with the
certificate, unlike DH parameters.
Is my understanding correct?
Thanks,
